Intel® Embedded Graphics Driver FAQ

Linux*

1.  Will Intel® Embedded Graphics Drivers 10.4 Gold work on Fedora* 12 or Fedora 14?


Intel® Embedded Graphics Drivers 10.4 Gold (build 1839) does not work with Fedora 12 or Fedora 14. It requires driver changes and building a new Intel® Embedded Graphics Drivers kernel module.


2.  What is the EDID-x.bin file? How is it used?


This is an older configuration capability that was available for configuring the Linux* version of the Intel Embedded Graphics Drivers. Although this is compatible with the newer releases, it is recommended that you use more current configuration mechanisms. See the user guide for more information on the most current ways to configure the Linux version of the driver.


3.  One of the newest features in Intel® Embedded Graphics Drivers is a Linux Installer for Fedora* 7 (excluding the Intel® System Controller Hub US15W chipset). When is support (installer and drivers) for Fedora 10 planned?


Intel Embedded Graphics Drivers 10.2 drivers support the Fedora 10 operating system. Successful manual driver installation can be completed using instructions found in the latest user guide.


A Linux Installer for Fedora 10 does not yet exist.


4.  What Linux Fedora 7- and Fedora 10-based applications can be used to obtain key information about a video file such as its bit rate, codec, whether hardware acceleration on the Intel® System Controller Hub (Intel® SCH) US15W chipset is on or not, and so on?


VAInfo* and MediaInfo* applications are recommended for this purpose.


Note: the Intel® SCH US15W chipset is the only chipset that currently supports Video Decode Hardware Acceleration; however, future embedded chipsets will have this capability as well.


5.  Do Intel® Embedded Graphics Drivers support kernel mode setting features on Fedora or Moblin*?


No. Intel® Embedded Graphics Drivers do not support Kernel Mode Setting features on any platform on any Linux flavor (as of Intel Embedded Graphics Drivers 10.3 and earlier versions or in the near future).


6.  Are there any plans to provide a new Intel® Embedded Graphics Drivers Linux installer that supports all POR Linux distributions?


No, Intel Embedded Graphics Drivers v10.3 has an installer/uninstaller for Fedora 7. Please refer to the user guide for installation instructions on other supported Linux distributions.


7.  What are the currently supported Linux distributions with Intel Embedded Graphics Drivers 10.3.1?


This depends on the chipset being used.


The Intel® SCH US15 chipset supports:

  • Moblin* 2.1 IVI: kernel 2.6.31, X Server 1.6.4-901
  • Fedora* 10: kernel 2.6.27-5, X Server 1.5.3
  • Ubuntu Hardy* for MID 8.04: kernel 2.6.24.3, X-Server 1.4
  • RedHat* Embedded: kernel 2.6.23, X-Server 1.3
  • Wind River* Autograde: kernel 2.6.21, X-Server 1.3


Intel® Atom™ processor 400 and 500 series supports:

  • Fedora 10: kernel 2.6.27-5, X-Server 1.5.3


All other supported Intel® Embedded Graphics Drivers chipsets support:

  • Fedora 10: kernel 2.6.27-5, X-Server 1.5.3
  • Fedora 7: kernel 2.6.21-1.3194, X-Server 1.3


Note: The above X-Server versions correspond to the Intel® Embedded Graphics Drivers Linux Xorg-xserver directories that contain the drivers when the Intel® Embedded Graphics Drivers Linux package is expanded.

8.  How do I install Fedora* 10 and Intel® Embedded Graphics Drivers on a platform based on the Intel® System Controller Hub US15WP/WPT chipset from the ground up?


Review document 324962, Application Note: Installing Fedora* 10 for Platforms Based on Intel® Atom™ Z510/Z520/Z530 Processor + Intel® US15W System Controller Hub.


9.  How do I install Fedora* 10 and Intel® Embedded Graphics Drivers on the Customer Reference Board (CRB) for the Intel® Atom™ processor 400/500 series named "Moon Creek" from the ground up?


Download or request document number 452607, "Installing Fedora 10 for Moon Creek."


10.  Now that I have installed Linux, how do I clone it?


Download or request document number 449300, "Cloning Linux* Drives Using MondoArchive."


11.  What's a good benchmark test for GL on Linux?


Often, glxgears is suggested as an easy way to see that GL is working. The nice thing about it is that it comes with most Linux distros. Unfortunately, glxgears does not exercise GL much so it's not a good GL benchmark. Its Frames per Second (FPS) report only measures copying from the render buffer.


Instead, use "glblur -fps" or "sierpinski3d -fps" to rigorously test the graphics system. These programs come with the xscreensaver suite (Please see http://www.jwz.org/xscreensaver but download the binary from your distro's repository or from http://rpmfind.net/Linux/rpm2html/search.php?query=xscreensaver).


The -fps option shows the CPU load figure with the FPS report. Glblur keeps the CPU load high but steady. Sierpinski3d* varies its load with the number of polys it uses. When its polys go up to 4,096, the load rises higher than glblur's load and sierpinski3d's FPS drops.


12.  What is the supported Linux distribution for Intel® Atom™ processor 400 and 500 series?


Currently, the only supported Linux distribution for platforms based on the Intel® Atom™ processor 400 and 500 series is Fedora* 10, kernel 2.6.27-5: X-Server 1.5.3.
